Abstract (en)
A dual fuel injector (12) may be used to injector both gas and liquid fuel into a cylinder (7) of a compression ignition engine (5). An injector body (70) defines a first set of nozzle outlets, a second set of nozzle outlets, a first fuel inlet (33) and a second fuel inlet (36). A dual solenoid actuator (100) includes a first armature (101), a first coil (102), a second armature (103), a second coil (104) and a lever (140). The dual solenoid actuator (100) has a non-injection configuration at which the first armature (101) is in an un-energized position, the second armature (103) is at un-energized position and the lever (140) is at a first angular orientation. A dual solenoid actuator (100) has a first fuel injection configuration at which the first fuel inlet (33) is fluidly connected to the first set of nozzle outlets, the first armature (101) is at an energized position, the second armature (103) is at the un-energized position and the lever (140) is at the first angular orientation. The dual solenoid actuator (100) has a second fuel injection configuration at which the second fuel inlet (36) is fluidly connected to the second set of nozzle outlets, the first armature (101) is at the un-energized position, the second armature (103) is at an energized position and the lever (140) is at a second angular orientation. The dual solenoid actuator (100) may also include a combined fuel injection configuration.
